Is your Mercedes ignition refusing to recognize your key? You slide the key into the dash, but there’s no "click," no turn, and no life. Whether a low battery corrupted the memory or a jump-start caused a power surge, a bricked EIS (Electronic Ignition Switch) can turn your luxury car into an immovable object. Dealerships will tell you a new unit is your only option, costing you thousands. At ClusterFix Texas, we offer the "Best of Both Worlds": we repair or clone your existing module to get you back on the road for a fraction of the cost.

The Experiential Truth of "Plug & Play"

Imagine the relief of receiving your EIS back, sliding it into the dashboard, and hearing that familiar, crisp engagement as the key finally turns. The dash glows, the engine fires up, and your Mercedes feels like itself again. No "Dealer-Only" programming, no towing, and no expensive SCN coding. From the Hill Country to the Gulf Coast, we provide a 100% plug-and-play solution that preserves your car’s digital identity.

HOW IT WORKS (The Shipping Checklist)

1. The Service: We diagnose, repair, or clone your EIS/EZS module. If your unit is beyond repair, we can clone your data onto a donor module (matching part numbers required) or source one for you.

2. What to Pack:

• Your EIS (Ignition Switch): The module from your dash.

• Your Working Keys: We need these for bench-testing.

• A Donor EIS: Only if yours is unrepairable (must match part numbers).

• Note: If all keys are lost, we may need your Engine Computer (DME/ECU).

3. The Paperwork: Print and complete our [Service Form HERE]. Please include:

• Full Name, Phone, and Return Address.

• Vehicle Year, Model, and VIN Number.

• Symptoms (e.g., "Key won't turn" or "No remote response").

4. Ship to the San Marcos Lab: Package your modules safely with at least 6 inches of bubble wrap.
